Tackle & technique
- Kelp greenling
- Kelp greenling are solitary bottom fish of rocky shores, jetties and kelp beds, usually in water shallower than 60 feet. Use a small number 4 to 6 hook with sand shrimp or marine worms, or a small lead-head grub, dropped to the bottom and reeled up slightly. Larger fish show in October and November when they spawn close to shore, and mornings tend to fish best.
- Surfperch
- Surfperch feed in the troughs and holes within about 30 feet of the waterline, just outside the first set of breakers. Cast a two-hook high-low or Carolina rig with size 4 to 2 hooks and a 1 to 6 ounce pyramid sinker and let the surge work it through the trough. Fish the incoming tide on beaches with a steep drop, and switch to jetties, pilings and bays when the surf is too big.
- Leopard shark
- Leopard sharks cruise shallow mudflats, sloughs and channel edges in bays, most often in less than 15 feet of water, and follow the flooding tide onto the flats to feed on crabs, worms, clams and small fish. Anchor or fish from shore or a pier with a sliding sinker rig and a chunk of squid, mackerel or ghost shrimp on the bottom. The bite is often better into the evening and at night.
